Head rest for the seat of a vehicle

Abstract

In the case of a head restraint which is connected to the backrest (5) of a vehicle seat, a padded segment (9) which can be changed in position relative to the basic body (1) of the head restraint can be shifted, in the event of an accident, under the action of a force-generating device from the use position toward the seat occupant's head (10) into a safety position and can be locked therein by means of a fixing device. According to the invention, the fixing device comprises a telescope (11) which, on the one hand, is supported on the basic body (1) and, on the other hand, is connected to the shiftable padded segment (9), it being possible for the resetting forces (FR) which act on the padded element to be introduced into the telescope in a direction deviating from the telescope axis (X).

AI Technical Summary

Benefits of technology

"The invention is a head restraint for vehicles that includes a telescope and a padded segment. The telescope is supported on a basic body and connected to the padded segment through a force-transmitting device. The force-transmitting device acts on the telescope to prevent the padded element from shifting back. The telescope is inclined with respect to the horizontal and can be blocked when the vehicle is in motion. The telescope is made up of multiple tube sections that can be deformed when loaded eccentrically or obliquely. The force-generating device uses compression springs to generate a centrically acting force without deforming the telescope. The head restraint can be adjusted in height and rotation to provide a comfortable setting."

Problems solved by technology

Latching devices of this type are structurally complex and furthermore cannot be latched in an infinitely variable manner.

It can therefore not be ruled out that the latching is not securely engaged in the supporting position.
